Emergency HVAC Services

Not every HVAC issue requires an after-hours call, but some absolutely do. Here is how to know when to call us immediately versus when the problem can wait until the next morning.

Call us right now if any of these apply:

Complete system failure during extreme temperatures. A home in Knoxville without air conditioning during July or August can reach dangerous indoor temperatures within hours, particularly for elderly residents, infants, and anyone with a medical condition. A home without heat during a January cold snap is equally dangerous. These are medical-risk situations, not inconveniences. We respond to them immediately.

You smell gas near your HVAC equipment. A gas odor near your furnace, heat pump, or any connected appliances is a life-safety emergency. Leave the building immediately, do not operate any switches or devices, and call your gas utility and then us. Our technicians are trained to identify and address gas-related HVAC issues safely.

You smell burning or see smoke or sparks. An electrical burning smell, visible smoke from a vent, or sparks from any part of your HVAC system means shut the system off at the thermostat or breaker immediately and call us. These symptoms indicate electrical component failure that can escalate to fire damage.

You suspect a carbon monoxide issue. A cracked heat exchanger in a gas furnace can allow combustion gases including carbon monoxide into your living space without any visible sign. If your CO detector has alarmed, if anyone in the home is experiencing headaches or nausea while the furnace is running, or if your furnace is old and producing weak heat, treat it as an emergency. Get everyone out and call us.

You have a refrigerant leak. Hissing sounds from the indoor or outdoor unit, ice forming on refrigerant lines, or a sudden drop in cooling performance can all signal a refrigerant leak. Refrigerant is harmful to human health and the environment and requires immediate attention from a licensed technician.

Your system fails and you have no alternative. If you have no backup heat source and temperatures are forecast to drop below 40 degrees overnight, that is an emergency for your pipes as much as for your comfort.

Can wait until business hours: Unusual noises that are not accompanied by other symptoms, a system that is running but slightly less efficiently than normal, or an older unit that is struggling but still conditioning the air. These are worth scheduling promptly but are not 2 a.m. calls.

We handle every type of residential and commercial HVAC emergency throughout Knox County and the surrounding East Tennessee region.

Emergency AC Repair in Knoxville, TN

An air conditioner that stops cooling during a Tennessee summer needs same-day attention. The most common emergency AC failures we respond to across Knoxville and surrounding communities include total system failure, compressor failure, refrigerant leak causing complete loss of cooling, blown capacitors preventing startup, condenser fan motor failure causing the outdoor unit to overheat and shut down, and frozen evaporator coils blocking all airflow. We carry the components most frequently needed for these repairs on every truck and complete most emergency AC repairs the same day we are called.

Emergency Furnace Repair in Knoxville, TN

A furnace that stops heating in winter is an emergency, particularly for homes with young children, elderly residents, or pets. We diagnose and repair emergency furnace failures including ignitor failure, cracked heat exchangers, gas valve faults, blower motor failures, control board failures, and limit switch trips caused by overheating. Heat exchanger cracks are treated as an immediate safety issue in our shop because of the carbon monoxide risk they carry.

Emergency Heat Pump Repair in Knoxville, TN

Heat pumps are the dominant system type in East Tennessee homes. When they fail in heating mode during a cold stretch, the consequences are the same as a furnace failure. We respond to emergency heat pump calls for reversing valve failures, refrigerant loss, defrost cycle problems, compressor faults, and auxiliary heat strip failures that leave you without backup heat. If your heat pump is blowing cold air in heating mode or has stopped responding entirely, call us.

Emergency Ductless Mini-Split Repair in Knoxville, TN

Mini-split systems can fail at any hour and throw fault codes that shut the unit down completely. We respond to emergency mini-split calls for refrigerant leaks, outdoor unit failures, communication faults between indoor and outdoor units, and drainage emergencies causing water damage. We service all major brands including Mitsubishi, Daikin, Fujitsu, LG, and Samsung.

Emergency Commercial HVAC Repair in Knoxville, TN

A failed HVAC system in a commercial building means lost productivity, uncomfortable customers or employees, and in some cases regulatory compliance issues for food service or medical facilities. We provide emergency commercial HVAC repair for offices, retail spaces, restaurants, warehouses, and medical facilities throughout Knoxville and Knox County. We understand the urgency of commercial failures and prioritize response time accordingly.

Emergency Heating Repair Across East Tennessee

Beyond Knoxville, we dispatch emergency heating and cooling repair technicians throughout Blount, Anderson, Sevier, Loudon, Jefferson, Morgan, and Roane counties. If you are in Maryville at midnight with no heat, or in Sevierville on a Sunday with no AC, call (865) 933-5538. We will come.

When you call us for an emergency, here is exactly what happens.

We answer the phone. There is no voicemail during emergency hours and no call center routed overseas. You reach a person who can dispatch a technician.

We ask you a few quick questions over the phone. These help the technician understand what they are walking into and ensure they bring the right parts. If your situation sounds like a safety emergency, we walk you through the immediate steps to take while the technician is en route.

Your technician arrives in uniform in a marked vehicle. Before touching anything, they listen to what you have observed and when the failure occurred. Then they run a complete diagnostic.

Once the cause is identified, they explain it plainly and give you the exact cost to repair it before starting any work. No surprises on the invoice. If the repair requires a part we do not have on the truck, we tell you immediately and give you a realistic timeline. We do not make promises we cannot keep at 11 p.m.

After the repair, we test the system through a complete cycle to confirm it is operating correctly. We leave the work area the way we found it.

There are a lot of HVAC companies in Knoxville. When it is 2 a.m. and your furnace is out, the difference between them becomes clear fast. Here is what sets us apart.

We actually answer. No voicemail, no 48-hour callback window. Our emergency line is staffed around the clock.

We are local and licensed. We are based in Knoxville at 2501 Byington Beaver Ridge Rd and have served this community for three generations. Our owner is NATE certified. Every technician who comes to your home works directly for us. License #48048.

We carry parts. We stock the components most commonly needed for emergency repairs on our trucks. That means same-day completion on most calls instead of a diagnosis visit followed by a return trip.

We give you the price first. Every emergency call includes a diagnostic and a written estimate before we touch anything. You approve the work before it starts.

We handle everything. One call gets you a licensed HVAC technician for emergency AC repair, emergency furnace repair, emergency heat pump service, emergency mini-split repair, and emergency commercial HVAC — all from the same company.

Financing is available. An emergency repair that hits unexpectedly is stressful enough without the financial pressure of paying everything out of pocket the same night. We offer financing through Wisetack with up to 24 months no-interest so you can get the repair done and manage the cost over time.

Knox County: Knoxville, Farragut, Powell, Corryton, and all Knox County communities.

Blount County: Maryville, Alcoa, Friendsville, Greenback, and Louisville.
